Indium selenide precursor films

Antimony telluride films have been grown from antimony(III) and tellurium(IV) oxides.167 Antimony telluride films were stoichimetric and consisted of nanoscale particles of the size 100 nm. The films had a good crystallinity.167 Indium selenide films were grown from indium sulphate and selenium oxide precursors.168 The films consisted of large particles, 70 to 200 nm in diameter. The band gap was 1.73 eV.168... 

The approach to HTSC electrosynthesis described in this section is entirely analogous to that used for the production of semiconductive films such as CujcInj,S(Se)j [205,206]. The thermal treatment of electrodeposited metallic precursors carried out in an H2S(Se) atmosphere in some cases proved more successful than the cathodic codeposition of sulfur or selenium with the metals [207]. There is also an analogy with other combined methods of selenide preparation the sputtering of copper or indium followed by cathodic deposition of selenium [208], and the chemical reaction of selenium with metals. In this case, as in the deposition of incomplete HTSC precursors [189], the use of the deposition mode is much easier.
